After an extensive three day investigation, police have made an arrest in the shooting of a 20-year-old Oil City man.

Oil City Police, with the assistance of Polk Police Department and PA State Police, arrested 32-year-old Nathaniel Curtis Conn, of Oil City, in connection with the shooting of 20-year-old Shane Oneal Davidson at an apartment on Beach Street in Oil City.
